Question

Write a method named showChar. The method should accept two arguments: a reference to a String object and an integer. The integer argument is a character position within the String, with the first character being at position 0. When the method executes, it should display the character at that character position. The method does not return anything. Here is an example of a call to the method: showChar("New York", 2); In this call, the method will display the character w because it is in position 2. Demonstrate the method in a complete program. Sample Run java Method_showChar Enter a line of text: The elevation of Mount Everest is 29,029 feet (8,848·in·meters)↵ Enter yourindex:3 5↵ 9↵

Answer 1

A complete program with the method ShowCar:

import java.util.Scanner; // header file

public class ShowChar

{

public static void main(String[] args)

{

String lnOfText;

int i;

Scanner input = new Scanner(System.in);

System.out.print("Enter a line of text:");

lnOfText = input.nextLine();

System.out.print(" Enter your index: ");

i = input.nextInt();

show_Char(lnOfText,i);

}

public static void show_Char(String str_a, int i)

{

System.out.print(str_a.charAt(i));

}

}

In this program, both the inputs ie. a sentence or line of text as well as the index position is obtained. A method is written to find the string at that particular position. Finally the method prints that character at the particular index.
